Re: How to adapt to temp changes?
If you will keep you loads cool and out of the sun and heat while developing them they are more likely to be consistent during the colder months. If you do not let a cartridge sit in a hot chamber more than 15 seconds before firing it will help also. If the rifle is finicky about the load and you are working in a very narrow band of powder charge then it may lose accuracy in the colder temperature. Basic rule is to recheck the load once cold weather arrives. When hunting in cold weather keep some bullets in your shirt pocket so they will be warm and use them for long range shots over 500 yards. Under that range you won't see much difference from powder temperature effects for hunting purposes.
